ROBERT BABBOUR, 0F PATERSN, NEW JERSEY.

To all 'whom t may concer/nr.'

lie it known that ll, loenn'r Bannonn, a citizen of the United States, residing at Paterson, in the county of Fassaic and lState of New Jersey, have invented certain new and useful improvements in Forceps, of which the following is a specification.

In surgical operations where arteries are to be severed and tied, the surgeon after severing' an artery temporarily seals it by clamping it in a pair of forceps having means to lool; its aws closed and afterward permanently ties it with a piece of ligature which he cuts olf from a suitable length of that material: more particularly, the usual procedure is to temporarily seal up each artery, when severed, by means of a pair of forceps and after they have all been severed and thus sealed, leaving` the forceps all clamped on the arteries, then tie them up permanently one after ans other. Each tying operation is a slow and tedious process because the noose or cincture is not previously prepared but is formed at the time by passing; the lig-ato re around the artery and tying` it, and the delay thus involved sometimes becomes a very serious factor in extending the period under which the patient must be lrept anesthetized. The object of my invention is to provide means whereby to facilitate and expedite the tying' of arteries or the performance of any other worlr of that nature.

Figure l is a side elevation of an implement embodying' my invention;

Fig. 2 is a similar View showing the forceps closed on an artery and one of the constrctive nooses, of which several are shown by way of example, being' slipped od the forceps onto an artery gripped by the forceps; and

Fig'. 3 is a sectional view on line 3-3, Fig. 2.

c and o denote the gripping members of a pair of forceps, they being` pivoted tos lether at c and a and o designating' their jaws and e b their handles.

Member a, is formed substantially the same as one of the members in any ordinary pair of forceps.

Member b is shown in furtherance of my invention as constructed as follows:A Be tween the pivot c and the handle b this member is widened to produce a blade or FUBCEPS.

i Application filed September 30, 1920. Serial No. 413,911.

iin-like portion l which affords an elevation c whose summit extends longritndinallyT of the member, said member also havinguat f a stop to limit the openingmovement of the other member. @n the member o, shown for example riveted thereto, is clip g, say of sprins;v material, which preferably elftends parallel with and opposite said elevation, its free end projecting,Y toward the jaw end of the forceps.

o l1 designate the usual lugs which upon being` sprungpast and hooked `over each other hold the forceps jaws locked closed, asin clamping an artery.

7i designates the constrictive nooses. litaoh may be produced by forming` a loop in a suitable length of ligature and twistingits ends around each other, twice, leaving; the ends projecting, as shown, so that can be readily gripped in constrictingthe noose on the artery and tying a knot.

rlhese -nooses are 'slipped over the jaw end of the forceps and then under the clip s0 that they will be held clamped between the clip and the elevation e in suitably spaced or successive arrangement; its each artery is to be tied, having` gripped the same with the forceps as shown in Fig. 2 (where v1 indicates the artery held by the forceps), the nearest noose 7L is slipped clear of the clip and over the laws onto the artery.

So far as l am aware it is quite new to combine with forceps a constrictive noose or nooses arranged to embrace the same so as to be readily slipped ofi the forceps onto the artery or other part to be gripped, the forceps having1 means to hold the nooses releasably assembled therewith. It will be apparent that with such an implement the work of tyingarteries becomes greatly facilitated and expedited, and in many instances instead of encumbering the wound with a number of forceps one pair will suf nce for an entire operation.

lt will be noted that the holdingmeans afforded in the present example by the clip extends short of the free end of the jaw of the member on which it is arranged. llt is not new to provide a ligature holding means on one of the members of a pair of forceps, but it vis new to arrange said means, as stated, so as to extend short of the free end of the jaw of the member on which it is arranged; this not only preserves a clear leasably held thereon as hereinbefore set forth, but 1t affords an interim of freedom to each ligature which is very helpful at the moment of transfer thereof from the vholding means, as g', to the artery. By actuu ally placing the holding means at the handle side oi the pivot c the matter of facility in removino' the liOfatures when re uired is in 2": b 7

addition, enhanced. Y

The parallel arrangement of the clip with respect to the surface of the member o with which it coacts jorme a crotch oi uniform .vidthv from end to end and so insures all the liga-tures being held with the same pressure and so properly spaced from each other` The elevation e is provided principally so as to extend transversely or widen the partl or" the 'forceps which isV embraced by the succession of nooses, so that too much of each noose will not be free and so be likely to become disarranged or unduly distended in handling. v

lt will be understood that the stop prevents the forceps from being' opened so :Ear as to distend the loops. Y

Having thus fully described my invena ligature.

2. A. pair of gripping forceps having spring means supplemental to its gripping jaws to releasably Vgrip and thereby holdV thereon a ligature.

3. A pair of o'ripping forceps having supplemental to its gripping jaws a ligature clamping clip 0n and projecting toward the free end of one of said jaws and terminating back of such free end.

et. The combination, with a pair of foroeps, of a constrictive noose arranged in embracing relation thereto, the forceps having a clip on one of its coacting gripping mein. bersprojecting toward the jaw end thereof and holding the noose pressed against the adjoining surface of said member.

5. A pair of forceps having one member relatively back of the forceps pivot of appreciably greater width than the other, measured transversely vof such pivot, said forceps having means to releasably hold a constrictive noose thereon.

ln testimony whereof I aix my signature.
